TAM Air from TA Instruments can be configured with an 8 or a 3 channel calorimeter block and is designed for sensitive and stable heat flow measurements. It is an ideal tool for large scale calorimetric experiments requiring sensitivity in the milliwatt range. The operating temperature range is 5 °C – 90 °C. All calorimetric channels are of the twin type, consisting of a sample and a reference chamber. The 8 channel calorimeter will accommodate ampoules with a 20 mL volume. The 3 channel calorimeter will accommodate ampoules with a 125 mL volume. The thermostat employs circulating air and an advanced regulating system to maintain a very stable temperature within ±0.02 °C. The high stability of the thermostat makes the calorimeter well-suited for heat flow measurements over extended periods of time, e.g. weeks. The TAM Air is the recognized standard in the research and development, as well as quality control during cement and concrete manufacturing and preparation. With the higher volume ampoules, the TAM Air can also be utilized in food and environmental science applications.
